A coin that has Clashed Die "marks" shows the result of damage that occurs when the
obverse and reverse dies slam together with no planchet in the collar.

Bent planchets when fed into a hopper-feeder will jam,
preventing planchets from being placed in coining chamber.

The most vulnerable areas to clash marks are the highest areas on the face of the die, and these are the fields- the area that is lowest on the struck coin. The "mark" occurs where the design elements of the opposite die contact fields on the affected die, leaving its impression.

Canadian dies are slightly convex and clash marks from an opposing dies design will
always appear strongest in the fields closest to the center of the affected dies.

The opposite is true on dies that are slightly concave, such as some issues of Canadian coins (prior to 1937) and currently by many foreign mints around the world. On these types the clash marks will always appear strongest in the fields closest to the edge of the die.

On dies that are totally flat, neither concave nor convex, the clash marks appear uniform across the fields.

Since new modifications to presses (1980), that enable presses to disengage dies if no planchet is fed,
these varieties are seldom seen anymore.
